For example, the frame size is 20KB. So if you have 30fps, then the bitrate would be 4.8Mb/s (20KB x 30fps x 8 bits / byte). Frame sizes for modern H.264 are highly misleading and I recommend not to use them.

The size of each frame depends on many factors, but it may be assumed that the size of P frames is about 60% of the size of I frames, and B frames may be reduced even to 10% of the size of the I frames. Compressed video stream. Decompression sequence. The H.264 algorithm is complicated.

• The standard also specifies intraframe coding for 8x8 blocks, and the reference software uses 8x8 blocks rather than 4x4. Criteria 3: Determine the ratio of total frames to I frames. A big part of H.264's power comes from P frames. These are the frame that only 'predicts' the progress or changes over the last fraction of a second. While the size of P frames may vary (depending on scene complexity/changes), usually P frames are far smaller than i frames.

It looks like we're storing 300 times the amount of data in the video. B-Frames are not used in all modes of H.264. The encoder decides what type of frame is best suited. There are typically more P-frames than I-frames. Lab analysis has shown TelePresence I-frames to generally be 64K wide (50 packets @ 1316 bytes), while P- frames average 8K wide (9 packets at 900 bytes). Hope this helps Hi ashtnmike,Hello I am trying to render a - .mp4 / h.264 - 360 video in stereo (3840x3840) at 60fps I keep getting an "Invalid Framesize/rate for this level. Increase profile and level and try again"That seems to be a limitation with h.264I mean, even with the maximum level of 5.2 you can export in 3840×2160Please check this link: H.264/MPEG Then you must get one SPS frame.

H.264 I-Frame Only ENCODER FPGA Core - High Speed Micro Footprint Our I-Frame Only FPGA core is highly optimized to be as fast and small as possible. By limiting the core to using only I-Frames, we were able to reduce the size of the core by 30% (compared to our already small H.264 Encoder Core) achieving a size close to that of a JPEG Encoder, yet provide much better compression!

I have a comp Width 404 and height 600. Portrait framing not traditional tv framing. I would like to be able to supply a nice high quality H264 quicktime so clients web guys can convert and upload (in that pixal ratio) to a flash player.
